Made of Air founders Allison Dring and Daniel Schwaag were interviewed by Wired Germany on how biochar can improve the climate impact of building materials:
Allison: "Normally, rotting plants release the CO² that they have captured through photosynthesis. During the production of biochar CO² is permanently fixed in the material and therefore removed from the atmosphere for thousands of years. The problem is that there are currently far too few applications for biochar to achieve a global reduction of CO². We mix with biochar with polymers and build facades out of it."
Daniel: "Urban construction uses a lot of materials. If we could reduce the amount of CO² in the atmosphere through building, architecture would not have to justify its use of materials."
